Staff comments made during this phase of the application process may not be all-inclusive, as other issues may arise during the remaining application process. COMMENTS GENERAL PROJECT INFORMATION/LOCATION Project description: A Site Specific Development Plan and Use by Special Review Permit for a one -mile long 16 -inch High -Pressure Natural Gas Pipeline connecting the O'Connor Gas Plant (2MJUSR18-12- 1792) to an existing Kinder Morgan Meter Station in the A(Agricultural) Zone District. ACCESS For new accesses and/or change of use of an existing access, the fee and photos are required (photo looking left and right along roadway from the access point and looking in to and out of the access point). These photos are used to evaluate the safety of the access location. Access permit instructions and application can be found at https://www.weldgov.com/departments/public works/permits/. Chapter 6, Sections 6.3, 6.4 and 6.5 of the Weld County Engineering and Construction Criteria offer access design guidance, which can be accessed at: https://www.weldgov.com/departments/public works/engineering/. ROADS AND RIGHTS -OF -WAY Pursuant to CRS 43-2-110(1.5), County Road 49 is designated as a County Highway. The County Highway is designated on the Weld County Functional Classification Map (Code Ordinance 2017-01) as an arterial road, which requires a minimum of 140 feet of right-of-way, or 180 feet of right-of-way in some locations. Contact Public Works for the location of the current right-of-way alignment and easements so they can be delineated accurately on the map. If the right-of-way cannot be verified it shall be dedicated. The applicant shall also delineate the physical location of the road. Pursuant to the definition of setback in the Weld County Code, Chapter 23, Article III, Section 23-3-50, the required setback is measured from the future right-of-way line. This road is maintained by Weld County. Per Chapter 12, Article 4, Section 12-4-30.B, a Weld County Right -of -Way Use Permit is required for any project that will be occupying, constructing or excavating facilities within, and/or encroaching upon, any County rights -of -way or easement. Pipelines crossing a county road shall obtain a Right -of -Way Permit and possibly a Special Transport Permit. Pipelines crossing county roads shall be bored, unless otherwise approved by Public Works. Right -of -Way Use Permit instructions and application can be found at https ://www.weldgov. com/d epartments/publicworks/perm its/. Any oil and gas pipeline crossing an arterial road shall be bored a minimum of twenty (20) feet below arterial roads, fifteen (15) feet below collector and paved local roads, and ten (10) feet below gravel local roads. This depth shall be measured below the lowest roadside ditch flowline elevation, for the full width of the future right of way. Weld County will not replace overlapping easements located within existing right-of-way or pay to relocate existing utilities within the County right-of-way. TRACKING CONTROL POLICY Per Chapter 12, Appendix 12A.10.1, traffic volumes to the proposed facility may require the installation of a tracking control device and/or a minimum of four inches of compacted recycled asphalt or aggregate road base. Tracking control is required to prevent tracking from the site onto public roadways. Temporary Tracking Control shall be used during construction unless permanent tracking control is installed ahead of construction activities. Recycled concrete is not allowed in County right-of-way. Tracking control devices can be double cattle guards or rip rap (6" washed rock). Tracking control for unmaintained public right-of- way is required just prior to entering publicly maintained roadways. A variance request for alternatives to the tracking control requirement can be submitted to Public Works for review and consideration. IMPROVEMENTS AND ROAD MAINTENANCE AGREEMENT Public Works may require an Improvements Agreement for one or all the following reasons: • Off -Site Public Improvements • Road Maintenance Agreement • Construction Maintenance Agreement • Access Improvements Agreement An Improvements Agreement is required for sites with required offsite improvements per Chapter 12, Article 5, Section 12-5-60. Collateral is required to ensure the improvements are completed, and maintained. Improvements/Road Maintenance Agreement: An example agreement is available at: https://www.weldgov.com/UserFiles/Servers/Server 6/File/Departments/Public%20Works/DevelopmentR eview/sprusr.pdf. It will detail the approved haul route(s), outline when offsite improvements will be triggered, and include a maintenance agreement for the haul routes. Possible mitigations included in the road maintenance agreement may include but are not limited to: dust control and damage repairs. DRAINAGE REQUIREMENTS Pipelines are excepted from the requirements of a drainage report and detention pond design under 23- 12-30.F.1.a.5 for pipelines or transmission lines. MS4: This site is located in a Municipal Separate Storm Sewer System (MS4) Area which may trigger specific water quality requirements or other drainage improvements.

Questions pertaining to the MS4 requirements should be directed to the Public Works Department 970- 304-6496. GRADING PERMIT If more than 1 acre is to be disturbed for construction of non -pipeline items such as structures, parking lots, laydown yards etc..., a Weld County grading permit will be required prior to the start of construction. Grading Permit applications are accepted after the planning process is complete (plan recorded). An Early Release Request Form may be entertained only after the applicant, Public Works and Planning Department have reviewed the referral and surrounding property owner comments. The Early Release Request may or may not be granted depending on referral comments and surrounding property owner concerns. Contact an Engineering representative from the Public Works for more information. A Construction Stormwater Permit is also required with the State for disturbing more than 1 acre.

(Department of Public Works) WELD COUNTY DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT 1555 North 17th Avenue, Greeley, CO 80631 www.weldhealth.org Memorandum To: Chris Gathman From: Lauren Light, Environmental Health Services Date: June 28, 2018 Re: USR18-0055 DCP Operating Company, LP Environmental Health Services has reviewed this proposal for a Site Specific Development Plan and Use by Special Review Permit for a one -mile long 16 -inch High - Pressure Natural Gas Pipeline connecting the O'Connor Gas Plant (2MJUSR18-12- 1792) to an existing Kinder Morgan Meter Station in the A(Agricultural) Zone. Permanent water and sewer is not required as this request is a temporary construction use. Portable toilets and bottled water can be utilized during construction of the pipeline. As the amount of disturbed area does not exceed 25 acres an Air Pollution Emission Notice (APEN) is not required. We have no objections to the proposal; however, we do recommend that the following requirements be incorporated into the permit as development standards: 1. During construction, all liquid and solid wastes (as defined in the Solid Wastes Disposal Sites and Facilities Act, 30-20-100.5, C.R.S.) shall be stored and removed for final disposal in a manner that protects against surface and groundwater contamination. 2. During construction, no permanent disposal of wastes shall be permitted at this site. This is not meant to include those wastes specifically excluded from the definition of a solid waste in the Solid Wastes Disposal Sites and Facilities Act, 30-20-100.5, C.R.S. 3. During construction, waste materials shall be handled, stored, and disposed in a manner that controls fugitive dust, fugitive particulate emissions, blowing debris, and other potential nuisance conditions. The facility shall operate in accordance with Chapter 14, Article 1 of the Weld County Code. 4. Fugitive dust and fugitive particulate emissions shall be controlled throughout the duration of construction of the pipeline and until ground cover is established.
